Abstract
The utility model discloses a dust-removing system of high-temperature smoke gas media. An air outlet and an air inlet are respectively arranged at the upper end and the lower end of a smoke flue, the middle part of the smoke flue is communicated with a medium discharging opening of a medium box by an upswept pipeline, a high-temperature endurable dust-filtering plate and a smoke flue auger are sequentially arranged above the air inlet, the tail part of the smoke flue auger is connected with a charging opening of a medium purifying device, a dust-collecting device is arranged at the bottom part of the medium purifying device, the discharging opening of the medium purifying device is connected with the entrance of a medium transmitting device, and another medium discharging opening is arranged at the top part of the medium transmitting device. Smoke gas flows upwards in the smoke flue and meets a dust-removing medium when passing by the smoke flue, the residual dust in the high-temperature smoke gas is absorbed by the dust-removing medium, the dust-removing medium which absorbs dust is driven into the medium purifying device by the smoke flue auger, and the purified dust-removing medium returns to the medium box along with the medium transmitting device and returns to the smoke flue again to continue absorbing dust. Therefore, the purpose of removing dust is achieved by the above cycling.
Description
Technical field
The utility model discloses a kind of high-temperature flue gas medium dust pelletizing system, is a kind of flue gas ash removal treatment technology equipment of uniqueness, relates in particular to the device that a kind of high temperature fume dust removal purifies, and belongs to environmental technology field.
Background technology
At present, along with the development of industrial technology, all have every year in the tens billion of tons of industrial high temperature gas discharging atmosphere, these industrial high temperature gases are to be that fuel produces in combustion process with coal or heavy oil mostly, generally greater than 400 ℃, the dust concentration height, soot dust granule is thin, stickums such as tar are many, the easy dewfall of low temperature contains a large amount of grits and pernicious gas, directly discharging, serious atmosphere pollution can be caused on the one hand, a large amount of thermal waste can be caused on the other hand.
Existing industrial dedusting method comprises following several method substantially: cloth-bag type process of cleaning, high temperature cyclone dust removal method, Cottrell process and wet dust removal method etc., wherein, cloth-bag type process of cleaning maximum operating temperature is 280 ℃, has heatproof and acidproofization etching problem; High temperature cyclone dust removal method is because low to the removal of the foreign particle below 10 μ m efficient, even adopt multistage dedusting, its removal effect does not reach 98% yet; And Cottrell process not only consumes energy greatly, and dust removing effects is also very unstable.Adopt the wet dust removal method of cascade, not only can cause the waste of heat energy, can cause the secondary pollution of water simultaneously again.
Cleaner has following a few class by the mechanism of action: mechanical dust collector, electric precipitator, filtration dust catcher and scrubber four big classes.Mechanical dust collector comprises gravitational precipitator, inertia force precipitator and centrifugal collector three classes again; Wherein, mechanical dust collector, cheap, simple in structure, but efficiency of dust collection is low; Electric precipitator, the separative efficiency height can be removed particulate effectively, and the processing gas flow is big and resistance is low, be applicable to high temperature and corrosive gas, operating cost is low, but the investment cost height, equipment is huge, and floor space is big, device fabrication, installation, maintenance requirement height; Characteristic to dust is comparatively responsive; Filtration dust catcher only limits to handle the high-temperature flue gas below 250 ℃ at present, is quickening both at home and abroad various high-temperature filter materials are studied; The washing type deduster, power consumption is high, and produces new liquid waste.
In a word, existing dust collection method is difficult to satisfy the industrial high temperature dedusting and purifies requirement.
Summary of the invention
The utility model discloses a kind of high-temperature flue gas medium dust pelletizing system, has overcome the complex structure that existing deduster exists, the high shortcoming of energy consumption.
Technical solution of the present utility model is as follows: by flue, the flue screw feeder, high temperature resistant dust-filtering plate, medium box, the dense medium purifica tion device, the dust gathering-device, medium conveying apparatus, motor constitutes dust pelletizing system, wherein, the two ends up and down of flue are respectively equipped with gas outlet and air inlet, the middle part of flue is communicated with the medium discharging opening of medium box by acclivitous pipeline, in flue air inlet above be sequentially with high temperature resistant dust-filtering plate and flue screw feeder, the discharging opening of flue screw feeder is connected with the charging aperture of dense medium purifica tion device, the bottom of dense medium purifica tion device is provided with the dust gathering-device, the discharging opening of dense medium purifica tion device connects the inlet of medium conveying apparatus, be provided with the chain-bucket connecting gear in the medium conveying apparatus and be connected with drive motors, the top of medium conveying apparatus is communicated with the circulation canal that medium box constitutes the dedusting medium.
In described dust pelletizing system, the dense medium purifica tion device is an inclination pot type structure, is provided with the rotation inner core two ends that have sieve aperture in it and is respectively equipped with charging aperture and discharging opening.
Be provided with high temperature resistant dust-filtering plate above air inlet, this dust-filtering plate can carry out first step filtering to the dust in the high-temperature flue gas.Flue gas through filtering is up in flue, when the flue and the dedusting medium meet, residue dust in the high-temperature flue gas is adsorbed by the dedusting medium, under the drive of flue screw feeder, the dedusting medium of absorption dust is brought into the dense medium purifica tion device, and the dedusting medium after the purification is got back to medium box with medium conveying apparatus, is back to continue absorption dust in the flue again, so circulate, reach the purpose of dedusting.
Good effect of the present utility model is: utilize the dedusting medium that high temperature dust gas is carried out purified treatment, the dedusting medium can be recycled through after the decontamination cycle.It is not high to have overcome above-mentioned dust pelletizing system heatproof, and power consumption is big, causes shortcomings such as secondary pollution.This device can be handled high-temperature flue gas more than 600 ℃, be had higher operating pressure, and is particularly more remarkable to high-temperature flue gas final dusting effect.
